Application June 11, 1948, Serial No. 32,515

2 Claims. ((31.29-235) This invention relates to improvements in flexing tools for inserting and removing flexible window sash.

An object of the invention is to provide an improved flexing tool for inserting and removing flexible window sash in and from window frames.

Another object of the invention is to provide an improved flexible tool for inserting and re-' moving integral window panes and sash of flexible material in and from window frames.

A further object of the invention is to pro vide an improved flexing tool for use in removing and inserting integrally formed flexible window panes and sash in window frames, said tool be ing highly efficient in use and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

Figure l is an inside front elevation of a window frame with the upper inside sash bowed directly behind the lower inside sash and the improved sash flexing tool positioned over the upper and lower inside sash ready to flex and remove the same from the window frame.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. i.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. l, with the flexing tool and flexed sash shown in dotted lines ready to be removed from the window frame.

Fig. 4 is a front elevation of a window frame with the upper and lower outside sash disposed one behind the other with the flexing tool in position over the sash ready to flex and remove the sash from the window frame.

Fig. 5 is a plan view, partly in section, showing the flexing tool and outer sash flexed and ready to remove from the window frame.

Fig. 6 is an enlarged detail sectional view taken on the line 66 of Fig. l.

Fig. 7 is an enlarged detail sectional view taken on the line 'i'! of Fig. 4.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is shown and provided a substantially rectangular shaped window frame generally designated by the reference numeral l.

Vertically disposed corrugated sash supporting guide strips 2 and 3 are secured in the opposite sides of the window frame 5, and extend the full length or height of the opening provided therein for the upper and lower outer sash l and 5, and for the upper and lower inner sash and I.

The sash' l, 5, 6 and i are formed of plastic and are provided with integral right angularly extending grooved guide beads 8 which are disposed along the opposite vertical edges thereof. The guide beads t cooperate with the vertically disposed corrugated sash supporting guide strips 2 and 3 being vertically slidable and adjustable thereon.

The improved flexing tool comprises a pair of inverted U-shape sash flexing members 9 and I0 formed with depending forked arms H and I2 adapted to straddle the sash when slid thereover from the top. inwardly and downwardly extending actuating handles 23 and M are formed integrally with the transversely extending portions of the flexing members 9 and [0.

Combined connecting and rubber cushioning links [5 and G6 are secured to the adjacent depending arms of the flexing members 9 and ID in vertical spaced relation, and with the links disposed in opposed relation engageable with the upper and lower inner sash or the upper and lower outer sash.

The depending arms of the flexing members 9 and It adjacent the sides of the sash are also provided. with vertically spaced oppositely disposed sash engaging rubber cushioning pads I? and [8.

In operation when the outer sash 4 and 5 are to be removed, the flexing members 9 and H) are placed over the sash and the handles it and It moved towards each other, thereby flexing the sash and bowing the same outwardly and drawing the guide beads 8 away from the guide strips 2 and 3 so that the outer sash may be readily removed from the window frame I. When the inner upper and lower sash 6 and 7 are to be removed, the flexing members 9 and ill will be disposed over their top edges and the handles l3 and M moved laterally away from each other, thereby bowing the sash inwardly and drawing the guide beads 8 away from the guide strips 2 and 3 so that the inner sash may be readily removed from the window frame I.

Similar manipulation will enable the sash to be replaced in the window frame I.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction 3 may be resorted to without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A flexing tool for inserting and removing flexible window sash, comprising a pair of U- shaped flexing members arranged side by side, each flexing member embodying depending forked side arms adapted to be positioned over a sash and extending substantial distances over the sash, yieldable connecting members connecting the forked side arms of adjacent U-shaped sash flexing members, and handles extending from the U-shaped sash flexing members whereby the yieldable connecting links are flexed, moving the U-shaped sash flexing members with respect to each other.

2. A flexing tool for inserting and removing flexible window sash, comprising a pair of inverted U-shaped sash flexing members, each U- shaped sash flexing member embodyng elongated forked side arms adapted to be positioned over one edge of the sash being flexed, gripping the sash between said arms, rubber cushioning links fitted over the adjacent forked side arms, pivotally connecting the forked side arms, and laterally and downwardly extended handles formed integral with the U-shaped sash flexing members, whereby the sash flexing members are moved with respect to each other.
